Think of it as an X-ray without the film. Fluoroscopy allows real-time visualization of an X-ray image on a TV monitor. X-rays are continuously generated and passed through the imaged body part onto an image intensifier instead of X-ray film.
This technology of viewing the image on a closed circuit TV screen is used in a variety of general diagnostic radiology procedures, most often in evaluating gastrointestinal and genitourinary tract issues. It's also frequently used in interventional radiology such as angiograms, drainages and biopsies. Contrast agents such as Barium, Iodine and Carbon dioxide are used to improve the contrast for a more accurate diagnosis.
The radiation dose received during most standard X-rays is minimal with exposure kept as low as possible. Pregnant patients should avoid radiation exposure. When medically warranted, certain X-rays in pregnant patients may be preformed after safely shielding the fetus.
